Algorithmic approach to skin diseases of the ear.

Skin diseases of the external ear (auricle and external auditory canal) are not uncommon. The major findings include erythema, pain, edema, discharge, pruritus, and changes in the shape of the ears. Infectious diseases are quite common in infants and children, inflammatory diseases are more prevalent in adolescents and adults, while keratinocytic malignancies increase by age. The dermatologist can serve as a pilot for patients with dermatoses of the outer ear. When there are discharge and pain, collaboration with specialists for ear, nose, and throat is recommended. In case of infants and children, collaboration with pediatrics is recommended. Whenever a malignancy is suspected, a skin biopsy for histopathologic study is crucial. In any patient with discharge, microbiologic and mycologic investigations should be performed. For the best outcome, a multidisciplinary approach is the optimum. Early diagnosis and efficient treatment are the cornerstones of a good prognosis and the best way to limit complications.
